    Description

      After JDK-8275317, C2's SLP vectorizer has supported type conversion
      between the same data size. We can also support conversions between
      different data sizes like:
      int <-> double
      float <-> long
      int <-> long
      float <-> double

      A typical test case:

      int[] a;
      double[] b;
      for (int i = start; i < limit; i++) {
          b[i] = (double) a[i];
      }
